Application filed February 21, 1924. Serial No. 694,202.

To all whom it may concern: pose only and not for the heating of the 55 Be it known that we, WILLIAM J. 'I-IAND entire inner atmosphere of a garage. A still LEY and BURTON R. LAnAwAY, citizens of further object is to produce this heater in the United States of America, residing at simple form so that its cost of manufacture Jackson, in the county of Jackson and State is low, making it possible to market the same of Michigan, have invented certain new and at a low price.

There is thus enclosed between It is a primary object and purpose of our the end 3, partition 9, bottom 8 and section invention to produce a heater which is ab 3, a chamber 11 into which an air conduct- 45 solutely safe against fire danger irrespecing pipe 12 leads, below which a gaseous tive of how much gasoline or other fuel of fuel inlet plug 13 also leads into the chamsimilar character may come in contact with ber, a tube 13 being connected to the plug or be positioned adjacent it. Also one with 13 to furnish the gaseous fuel. It is evident which a low consumption of fuel is had sufthat fuel and air are both carried to the 50 ficient to keep the temperatures under an chamber 11 in which a combustible mixture automobile engine high enough for the of the same occurs. safeguarding of the I engine from freez- A tube 14 of smaller diameter'than the ing up either in its water, oil or greases, air inlet tube 12 .is designed to carry the the heater being designed for thispurminedairv and fuel frorn the chamberllto a burner mounted on and above the bottom 1 of the body, the tube passing through the partition 9 and extending upwardly at an angle to the horizontal. The burner has a bottom 15, ends 16 and 17- into the latter of which tube 14 is threaded, and sides 18, said sides and the end 16 at their upper edges being formed with a thickened flange 19 in which a groove is cut on the inner sides for the slidable reception of a thin plate 20 in which a large number of small holes are made. This encloses an interior space in the burner of comparatively large capacity for holding the combustible mixture, and the cross sectional area of the passage in the tube 14: is larger than the combined areas of the openings in the plate 20 so that there is always some pressure serving to force the mixture through the openings in plate 20, the passage therethrough being even and uniform; and the mixture of air and fuel is complete in the chamber 11, so that no additional air is required for complete combustion. The flame at the upper side of the burner is that produced by complete combustion, no air comes from the outside except through the pipe 12, and no ignition of gasoline fumes can be had from this burner in service, as all movement of the gases of combustion is away from the flame and there is no movementof any gases toward the flame except the mixed gas and air passing thereto to feed the same through the openings in plate 20.

A cover plate 22, preferably of cast iron is located over and closes the upper side of the body, it having two spaced apart baflle members 23 cast therewith and depending downwardly into the body substantially parallel with the ends 2 and 3. Screws 24 passing through the plate into the lugs 6 serve to releasably connect the plate to the body. Each end 2 and 3 has a portion left out at its upper edge and substantially midway between the ends thereof, making openings 25 under the overhanging edge portions 22 of the cover plate 22 for the escape of the exhaust gases of combustion. A tube 26 passes through one of said openings and thence downwardly and inwardly through one of the bafiies 23, its lower end coming above the upper side of the plate 20. This is for the purpose of lighting the burner, the gas when first turned on escaping from the burner through the plate 20 and upwardly through thetube so that it can be readily lighted at the outer end of the tube.

From this construction, it is apparent that a simple but very effective heater is produced fully capable of operating in the manner set forth in the general statement of the invention, That is, an absolute safeguard against igniting any of the fuel used with the engine is present, there being no possibility of combustible gases or liquids being carried to the burner flame from the outside. In fact, the current of inert exhaust gases of combustible passing through the openings at 25, serves as a smother to flame, putting the same out at once. Volatile and highly inflammable fuel may be used around the heater without danger, in fact may drip thereon from the engine. In practice'the air pipe12 extends about thirty inches from the body to which it is attached. This precludes any escape of inflammable material therefrom.

The burner is mounted on a lug 1 cast with the bottom 1 and a lug 15 cast with the burner bottom 15, with an attachment provided by the screw 21*, as shown in Fig. 1. The assembly of the parts is simple and easy. The invention is defined in the appended claims and is to be considered as comprehensive of all forms of structure coming within their scope.
